LOCK.

Specification of Letters Patent.

Patenten. nee. 2e, 1era.

Application filed July 24, 1911. Serial No. 640,058.

To all 'whom t may concern Be it known that I, EDWARD KLEINER, a citizen of the United States, residing at Chicago, county of C ook, and State of Illinois,

have invented certain new and useful Improvements in Locks, of which the following is a full, clear, and exact specification.

This invention relates more particularly to locks for doors, and the like, which close with reference to a jamb or similar relatively fixed member, and it has for its primary object to provide an improved and simple lock for this general purpose, having means whereby the locking element i5 which serves to hold the door against movement relative to the jamb will be caused to engage the j amb in such a way as to prevent the door and the jamb from being pried apart in a direction lengthwise of the line of movement of said locking element as it moves into and out of its locked position.

The invention consists in the features of novelty in the construction, combination and arrangement of parts which are shown in the accompanying drawings, described in the following specification, and more particularly pointed out in the claim.

In said drawings Figure 1 is a face view of a lock embodying this invention, the side of the casing being removed. Fig. 2 is a transverse section thereof on the line 2-2 Fig. 1 with the case intact. Fig. 3 is a fragmentary view of what is shown in Fig. 1, showing the bolt thrown or locked. Fig. 4

is a perspective view of the bolt.

In illustrating the invention a common form of door lock has been employed as an example of the many forms of locks to which the invention is capable of being applied, and while it may be applied to any locking member of the lock, in this exemplification it is shown as applied to the bolt which is operated by the key, rather than to the knob operated bolt or latch. When thus applying the invention to the key operated bolt, which is shown at 5, the same is provided with a shoulder or hook 6 at its outer end, and with means for causing the outer end of the bolt to descend after it is thrown and passes into its keeper 7, secured to the j amb 8, of usual or suitable construction, as shown in Fig. 3, whereby the door to which the lock is secured cannot be pried away from the jamb in a direction lengthwise of the plane in which the bolt 5 operates. In order that the bolt may be given this descending motion after its end has passed sufficiently into the keeper 7 to enable the shoulder 6 to engage with the latter, it is provided with a slot consisting of a horizontal portion 9 and an inclined or curved. portion 10 through which passes a fixed pin 11 having secure attachment to the casing of the lock, and thereby serving to guide the bolt first horizontally and then in a downward direction when moving in a locking direction and first upwardly and then in a horizontal direction when being unlocked. The pin 11 and usual stop 12 adapted to be engaged by shoulder 13 serve either singly or conjointly as a means of preventing the bolt from being pulled out beyond its normal position when locked.

"What I claim is:

The combination of a casing, a locking bolt capable of longitudinal movement to project its locking end beyond the casing and having its inner end formed to be directly engaged by a key to shift the bolt, said bolt having a cam slot, a pin in said casing cooperating with said cam slot to shift the locking end of the bolt transversely, a fixed lug in the casing, a shoulder on said bolt for engaging said lug to limit the outward longitudinal movement of the bolt, and a keeper adapted to be engaged by the projecting end of said bolt.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 27th day of June, A. D. 1911.

EDWARD KLEINER.
